ABSTRACT OF THE DISCLOSURE This invention relates to a low viscosity hydroxylated liquid polymer having polymerized therein a mercaptan compound containing hydroxyl and/or carboxyl group(s) in an amount sufficient to reduce viscosity and provide low peel property on the order of 10 to 25 ounces without significantly lowering the adhesive properties thereof, to a removable, low peel adhesive which is a reaction product of the liquid polymer and an isocyanate prepolymer, and to a substrate having deposited thereon said adhesive. The removable adhesive produces a clean 180° peel while maintaining good tack and shear and due to its low viscosity, it can be processed at 100% solids, i.e., without any solvent.
